[linux-audio-user] Newbie: Realtime kernel and THAC's rpms

by Ketil Thorgersen

Hi experts and geniuses. Please be gentle with a newbie who has been using mandrake linux for a couple of years, but has staid clear of recompiling kernels etc, and just been a happy user. Up until now I've been using windows as my DAW platform, having a degree in sound engineering and being a teacher at a teachers training college. Having followed the progress of the music-apps pretty closely and finally found some time, I decided to see if I might get my feet wet with linux as a DAW. Since I'm familiar with mandrake and found THAC's rpms(http://rpm.nyvalls.se/sound9.1.html) I decided to go that route. I've been lurking on this forum for a couple of months now, and hope to get some help here in the process. I got me a new harddisk for my DAW machine so that I wouldn't loose anything. Installed Mandrake 9.1 (just the basic stuff) Then I installed ardour, jack and the kernel-multimedia packages from THAC. I then tried to start jack with 'jackstart -d alsa -d hw:0' and got the following response: "jackstart: cannot get realtime capabilities, current capabilities are: =ep cap_setpcap-ep probably running under a kernel with capabilities disabled, a suitable kernel would have printed something like "=eip" I did a search on the google, and found out that someone had asked the same thing on this list, but the answer was: "look in the faq" - which I then did. And the faq say "recompile". I thought the idea of rpms was that I didn't have to recompile - but I'm probably wrong. I just want to make sure before i jump onto something which I'd rather not do - because it scares me... (I'm a teacher and hobby sound engineer, not a linux wizard, but I'd like to learn) So do I have to recompile? Another thing: I have the staudio dsp24 cport soundcard which was recognised and everything, but if anyone has a link or some tips on how to use this in the most effective way under linux I'd be very happy! In windows we have a virtual patchbay for attaching and rerouting the different ins and outs. How do I do this in linux? I'd be very grateful for all help! Best regards Ketil Thorgersen

[linux-audio-user] audiophile 2496

by jordan muscott

Hi all, Does this card work ok with the latest alsa? I had a quick look at this : http://alsa-project.org/alsa-doc/doc-php/template.php3?company=Midiman&card… which sais something about the spdif on the front box not working, which confused me slightly because I didn't realise the card had a frontbox. I presume the spdif works ok on the card itself? thanks, just being careful, Jordan.

[linux-audio-user] Cuuuuuute! ;)

by Frank Barknecht

Hi, this is sooo cute: http://www.sonicstate.com/articles/article.cfm?id=63 Could Ardour support it? The test's closing remarks are funny, too: "All in all it's hard not to like the CS-32, something this small is hard to criticize - kind of like being nasty to small children" ciao -- Frank Barknecht _ ______footils.org__

[linux-audio-user] HDSP and "play"

by BrbrOfSvl＠aol.com

Hi, Matt again. So if you remember I have this problem where my hdsp freezes any time I use play (or any app that utilizes the play program, like maybe (?) audacity...). When I use play, it plays the soundfile, but afterward, I can't open any programs that would use my soundcard (some open but say it can't find the device or that the device is in use). When I run "ps aux" there's no indication of play being there. However, when I run play and it gets to the end of the soundfile, I hear what sounds like an amp clip, and I get this: /usr/bin/play: line 205: 1686 Segmentation fault sox $volume $fopts $fopts2 "$filename" $arch_defines $device $effects The 1686 before the Segmentation fault seems to change depending on the soundfile (1802 is another I've had)... I'm not really sure what that number is. So I opened up my /usr/bin/play in vi to see what was in line 205 (I've displayed the last bit of the program): # If name is "rec" then record else assume user is wanting to play # a sound file. if [ "$program_name" = "rec" ]; then # Don't send data to stdout if they are reading from it. if [ "$filename" = "-" ]; then echo "Send break (control-c) to end recording" 1>&2 else echo "Send break (control-c) to end recording" fi sox $volume $arch_defines $fopts $device $fopts2 "$filename" $effects else sox $volume $fopts $fopts2 "$filename" $arch_defines $device $effects fi Line 205 is the final fi, but the line above that is the one that appears in the "error" message I get running play. Is there something in that line (or the rest of the program) that I should change to get it to work with my hdsp? I have an onboard nVidia soundcard that works with play just fine, and aplay works fine with both cards. Is it a problem in the play program, or maybe the alsa hdsp driver I'm using? Another thing I noticed is that when I use play, the signal is being sent to all the channels on the hdspmixer, whereas when I use aplay, it sends it just to the first two. What gives? Also, when this happens, I've been rebooting the machine... is there a way maybe to restart alsa instead? Thanks, Matt

[linux-audio-user] Jackd problems

by jjbenham＠chicagoguitar.com

Sorry if this has been aswered a million times or something. I don't know if this error message I am recieving is correct: Ardour/GTK 0.377.1 running with libardour 0.685.0 Loading UI configuration file /etc/ardour/ardour_ui.rc application linked against too wrong of a version of libjack. ardour: [ERROR]: No JACK server found. I lauch jackd as root like this: jackd -R -d alsa -d hw:0 -r 44100 -p 1024 -n 2 & or jackd -d alsa -d hw:0 then I launch ardour muse or any other jack enabled program it gives be the above errors. jackd gives me these errors: cannot read request from client bad hci new client a cannot create new client; a already exists cannot write connection response to client cannot complete new client connection process I am running Debian unstable. I don't know if it is just broken or if I am doing something wrong. I even created an .asoundrc. I don't know if that helped though. It looks like this: pcm.emu10k1 { type hw card 0 } ctl.emu10k1 { type hw card 0 } Thanks, Jeremiah

[linux-audio-user] applying patch for HDSP 9652

by Aaron Trumm

Hello all - Aaron here again well I promised progress - well I went and read about RPM so I'd know what the hell it was, and now am applying patch. I've got Fernando's kernel and ALSA source, and I've put the patch in /usr/src/redhat/SOURCES and edited the alsa driver spec file, adding that patch, (I had to manually create the redhat directory in /usr/src - it wasn't there and rpm wouldn't create it and following directions on http://ccrma-www.stanford.edu/planetccrma/software/recompilealsa.html but I'm getting this wonderful thing: bash: rpmbuild: command not found that was quite unexpected. I'm sure I'll figure this out eventually but I thought it'd be smarter and faster to ask - what is happening? do I have a partial RPM in my system? # rpm --version gives me: RPM version 4.2 well thanks - cya on the flipside! -- -------------- Aaron Trumm NQuit www.nquit.com --------------
